I did a saliva test for free from the website Patients Like Me. They covered the cost of everything. The results were pretty inaccurate, IMO - for most of the meds that never worked for me or caused bad side effects, the lab said my markers were fine. That test also did not test for MAOI’s which I was currently on. The only thing it was right about was Abilify being problematic.

My new(ish) pdoc said he has used the Genesight quite a bit but he’s not as optimistic about it as he used to be and does not administer it all that often anymore. The test is just not good enough at predicting which treatment ends up working (or not working) for his patients. He thinks it’s useful only in order to detect if someone has a definite genetic marker for en enzyme problem or an inability to metabolize medication across the board - i.e. someone who is new to psych meds and has tried 3 or 4 and they completely don’t work. (FWIW, I have not taken the Genesight)
